Exploratory Study of the Interest of MRI Susceptibility Weighted Imaging for the Pre-operative Assessment of Pelvic Endometriosis Extent

2017-06-15 01:23:21 | BioPortfolio


Knowledge of the precise location of endometriosis is essential for a successful surgical treatment. MRI Susceptibility-Weighted Imaging (SWI-MRI) yields high sensitivity for blood by-products detection. Since endometriosis lesions are haemorrhagic, and therefore rich in blood by-products such as hemosiderin, SWI-MRI could be useful in the pre-operative assessment of endometriosis, especially in superficial peritoneal lesion detection. The purpose of our study is to evaluate the performance of SWI-MRI for the preoperative work-up of endometriosis


Pelvic endometriosis is a cause of pelvic pain, dysmenorrhea, urinary symptoms and infertility. MRI is considered as the best imaging technique to detect and to predict the extent of the disease. Susceptibility Weighted Imaging is routinely performed to identify haemorrhagic lesions in brain MRI protocols and has proven to be a sensitive technique to detect blood by-products. A pelvic MRI protocol including SWI will be performed in all women addressed for diagnostic assessment or pre-operative work-up of endometriosis.

Exploratory study of geometric distortion correction of prostate diffusion-weighted imaging using B map acquisition.

Evaluation of prostate MRI relies on diffusion-weighted imaging (DWI), commonly distorted by susceptibility artifacts, thereby creating a need for approaches to correct such distortion.

Medical and Biotech [MESH] Definitions

The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.

A type of imaging technique used primarily in the field of cardiology. By coordinating the fast gradient-echo MRI sequence with retrospective ECG-gating, numerous short time frames evenly spaced in the cardiac cycle are produced. These images are laced together in a cinematic display so that wall motion of the ventricles, valve motion, and blood flow patterns in the heart and great vessels can be visualized.

The use of combination of imaging techniques or platforms (e.g., MRI SCAN and PET SCAN) encompassing aspects of anatomical, functional, or molecular imaging methods.

A technetium imaging agent used in renal scintigraphy, computed tomography, lung ventilation imaging, gastrointestinal scintigraphy, and many other procedures which employ radionuclide imaging agents.

Optical imaging techniques used for recording patterns of electrical activity in tissues by monitoring transmembrane potentials via FLUORESCENCE imaging with voltage-sensitive fluorescent dyes.
